The project will be helmed by Sajid Khan, who has earlier directed comedies like 'Heyy Babyy', 'Housefull' and 'Housefull 2: The Dirty Dozen'.
"The film promises to be a laugh riot, as the trio unleash total madness and confusion in their triple avatars," said a statement.
It will be shot extensively abroad.
